“I needed a gift but only had an hour to plan and build it - it also needed to have a medical theme.I had enough spare parts to build an MP3 player (having ordered two of everything for an earlier cassette tape MP3 player project - based onlonesoulsurfer’s classic Instructable) and a doctor’s play set which was surplus to requirement…This is a very simple project that is suitable for beginners however there are some dangers with LiPo batteries.Double check all connections Ensure there are no shorts Care for the battery properly”
